IMPROVEMENT IN CHURN POWER.

The Schedule referred to in these Letters Patent and making part of thesame To all whom it may concern:

' Beit known that 1:, RUTH N. SMITH, of the city, county and. State ofNew York, have invented a new and improved Ghurn Power; and I do herebydeclare the following to be a full, clear, and exact descriptionthereof, which will enable those' skilled in the art to make and use thesame, reference being had to the accompanying drawing forming part -ofthis specification, in which drawingy Figure 1 represents a sectionalfront viewof .this invention. p

Figure 2 lis a transverse vertical section of the same.

Similar letters indicate corresponding parts.

This invention relates to a chur'n power composed of a crankshaft,whicl1connects, by means of a bifurcated rod and a swivel head, with thedasher-stali,

' saidstai` being guided in a removable bracket, se-

cured to the flame of the churn powerin such a manner that the requiredreciprocating motion can be imparted to the dasher without creating muchfriction, and, furthermore, by means of the removable bracket and swivelhead, the operation of connecting a churn to or disconnecting it fromthe power is materially facilitated.

In the drawing-` The letter A designates a frame, made of metal or anyother suitable material, and provided with two bearings for thecrank-shaft B, which are geared together by cog-wheels a b, with ahand-crank O, so that, by the operation of said hand-crank, a rapidrotary motion can be imparted to the crank-shaft.

lo the clank of this shaft is attached a bifurcated rod, I), the arms ofwhich form the bearings for the gudgeons c of a head, d, which isperforated with a hole to admit the stad' e of the churn-dasher.

A pin, f, which passes transversely through the swivel-head d, andthrough the dasher-stafi, forms the connection between said head and thestaff, and compels the churn-dasher t-o follow the motion of the rod D.

- it can be held in position by a simple pin.

To the cross-bar g of the frame A is secured a bracket, h, which` isperforated with a hole to admit the dasher-staii, and to guide the samein its up and down motion. This bracket is secured to the crossbar g bya screw, which passes through a flange extending frorn the bracket andresting on the cross-bar, or said bracket may be constructed with twoflanges, capable of straddling the cross-bar, and, in this case, Ineither case the bracket his removable, and, if it is desired -todisconnect the churn from the power, the bracket is taken ou", and, byremoving the cover ofthe churn, the dasher can be readily brought insuch a position that it-s staff can he withdrawn from the swivel-head d,since this head allows of swinging the dasher out to the positionrequired for this operation.

From this description it will b'e readily understood how the dasher-of achurn is to be conncted to my power, and it will be. seen that, by thecombined action of the removable bracket h and the swivel-head d,.tixeoperation of connecting and disconnecting a churn tothe power ismateriallyfacilitated, and that churns of diierent sizes can be readilyoperated by my po wel'.

It must be remarked that the form of the frame canbe changed, so as toallow of introducing and removing the churn with ease and facility.

What I claim as new, and desire to secure by Letters lPatent, is v Thechurn and power, consisting of the frame A, the crank-shaft B, thebifurcated rod D, the shaft E, the gudgeons c c, the swivel-head d, thegearing a b, the crank C, the cross-bar g, bracket h, and churn, allcombined, arranged, and operating as described.

This speciication signed byl me this 26th day of February, 1870.

RUTH N. SMITH.
